To evaluate the possible value of the perfusion index (PI) as a tool for pain assessment. Methods: This prospective, observational study was performed with 89 patients underwent surgery with general anesthesia. The patients with visual analog scale (VAS) greater than 3 were grouped as M1, and patients with VAS≤3 and performed morphine were grouped as M2. After surgery patients with VAS greater than 3 were given 2mg morphine. Patients with VAS greater than 3 were given increments of intravenous morphine (2 mg) at 20 minute intervals until VAS less than 3. The correlation and difference between PI and VAS score values were evaluated before and after analgesic administration. Results: Significant changes were found in both PI values and VAS scores between M1 and M2 groups (2.80±0.77, 3.97±0.94, p less than 0.001; 6.60±1.20, 2.74±0.46, p less than 0.001) Despite no correlation was found between PI values and VAS scores of M1 and M2 groups, weak negative correlation was detected between differences in PI values and VAS scores among groups (r=-0.255, p=0.016). Conclusion: Perfusion index is a parameter that can be used in the assessment of postoperative pain and responses to analgesics.
评估灌注指数（PI）作为疼痛评估工具的潜在价值。方法：本前瞻性观察性研究纳入了89例行全身麻醉手术的患者。视觉模拟评分法（VAS）大于3分的患者分为M1组，VAS≤3分且使用吗啡的患者分为M2组。术后VAS大于3分的患者给予2mg吗啡。VAS大于3分的患者每隔20分钟静脉注射递增剂量的吗啡（2mg），直至VAS小于3分。评估镇痛药物给药前后PI与VAS评分值之间的相关性和差异。结果：M1组和M2组的PI值和VAS评分均有显著变化（2.80±0.77，3.97±0.94，p＜0.001；6.60±1.20，2.74±0.46，p＜0.001）。尽管M1组和M2组的PI值与VAS评分之间未发现相关性，但组间PI值差异与VAS评分之间存在弱负相关（r = -0.255，p = 0.016）。结论：灌注指数是一个可用于评估术后疼痛及镇痛药物反应的参数。
